7481f0978a arm64 libc: hide .cerror, .curbrk, .minbrk for WITHOUT_SYMVER
When symver is in use these are hidden because they're not listed in
the Symbol.map. Add an explicit .hidden so they are also hidden in the
WITHOUT_SYMVER case.

a48bd01151 Fix the types for the start, end, and count arguments to
arm_gic_fdt_alloc_resource. These were the old u_long where they should be
rman_res_t. Both of these are the same size on arm64 so this is just for
correctness, and would not have led to incorrect behaviour.

b03aadaffc Ensure the received IP header gets 32-bits aligned.
The FreeBSD's TCP/IP stack assumes that the IP-header is 32-bits aligned
when decoding it. Else unaligned 32-bit memory access can happen, which
not all processor architectures support.

f8a39033c2 Set the upper limit of the DMAP region to the limit of RAM as was found in
the physmap. This will reduce the likelihood of an issue where we have
device memory mapped in the DMAP. This can only happen if it is within the
same 1G block of normal memory.

bd3bce41db Deprecate using hints.acpi.0.rsdp to communicate the RSDP to the
system. This uses the hints mechnanism. This mostly works today
because when there's no static hints (the default), this value can be
fetched from the hint. When there is a static hints file, the hint
passed from the boot loader to the kernel is ignored, but for the BIOS
case we're able to find it anyway. However, with UEFI, the fallback
doesn't work, so we get a panic instead.

Switch to acpi.rsdp and use TUNABLE_ULONG_FETCH instead. Continue to
generate the old values to allow for transitions. In addition, fall
back to the old method if the new method isn't present.

Add comments about all this.

7cbd0a2953 Simplify building libpam and fix libpam.a not containing the modules since r284345.
The change in r284345 moved the creation of openpam_static_modules.o to
lib/libpam/static_modules but never managed to get them into libpam.a.

Move this logic to lib/libpam/static_libpam and have it create a static
library for libpam.a  The main lib/libpam/libpam will only create a
shared library.  No redundancy in compilation or installation exists
in this solution.

This avoids requiring a pass with -D_NO_LIBPAM_SO_YET.

name to the object's "path".  While the objects don't have real path
names, it's a filesystem-like namespace, which allows jails to be

signature of ata_res_sbuf().  Its use in the tree seems to be very limited,

9853d10411 Increase the arm64 kernel address space to 512GB, and the DMAP region to
2TB. The latter can be increased in 512GB chunks by adjusting the lower
address, however more work will be needed to increase the former.

There is still some work needed to only create a DMAP region for the RAM
address space as on ARM architectures all mappings should have the same
memory attributes, and these will be different for device and normal memory.

830f064f5c [urtwn] use/track the last good RSSI for a given node, rather than no RSSI.
Now that we're decap'ing A-MPDU frame, the firmware is only giving us
PHY status information for the whole PPDU, rather than duplicatig it
per frame.

So, we fake it by maintaining the RSSI that we saw in the node struct
and reuse it.

This prevents us from getting some pretty garbage looking default RSSI
values, which shows up as RSSI values of like "3" or "4" when doing
active traffic.

Tested:
